Revision d14775ddbb067bcfa6eca516d3cbe968a8c1334e authored by Pablo Galindo on 01 September 2020, 20:40:57 UTC, committed by GitHub on 01 September 2020, 20:40:57 UTC
When allocating MemoryError classes, there is some logic to use pre-allocated instances in a freelist only if the type that is being allocated is not a subclass of MemoryError. Unfortunately in the destructor this logic is not present so the freelist is altered even with subclasses of MemoryError.. (cherry picked from commit 9b648a95ccb4c3b14f1e87158f5c9f5dbb2f62c0) Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>
